The Greenwich Cannon, like Antifate TSD, is a setup invented by Mr. Greenwich. Because it takes exactly one bag (7 distinct pieces) to set up, the setup does not give a particular advantage once the setup is made.

Ideally, if you can do the T-Spin Double beforehand, you can the other pieces in such a way you can make a Perfect Clear. Assuming the T-Spin Double is already done beforehand, some of the best cases to stack for a Perfect Clear are shown, apart from the first few cases as the S piece can be placed either before or after the T-Spin. In most cases, it will require a J or L piece in the third bag.
Perfect Clear after 8 lines
Most variants here require placing the remaining piece(s) after the T-Spin Double.
- S → I and T → Z → L (28.33% PC rate, 2 solutions): This variation allows one to make a T-Spin Triple and a Perfect Clear in the third bag.
- S → LO and T → I (98.37% PC rate, 35 minimal solutions): You will always be able to make a Perfect Clear if you get the Z piece within the first 2 pieces of the 3rd bag.
- J → Z → O, S → L and T → I / L → SO, Z → J and T → I (96.03% PC rate, 19 minimal solutions)
